Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cleaning machines, in particular to an adaptive limiting mechanism for a cleaning machine and a cleaning machine. Background Technique
[0002] At present, in the cleaning industry, various contaminated cleaning objects, such as carriers like baskets, often need to be cleaned to achieve repeated recycling. And sometimes, in order to remove residual stubborn stains and foreign objects, it is necessary to set a relatively high spray pressure for the cleaning machine to effectively clean the dirt on the cleaning object, and at the same time use the high-speed air flow blown by the air knife to dry it.
[0003] However, due to the different heights of the cleaning objects, the existing cleaning machines are only simply provided with a limiting mechanism for the cleaning objects. Such a limiting mechanism cannot adaptively adjust the limiting height or pressing height, and can only limit and press based on the highest cleaning object. If different heights of cleaning objects need to be cleaned simultaneously in the cleaning machine, the limiting part of the existing limiting mechanism is blocked by the highest cleaning object, resulting in that other shorter cleaning objects cannot be fully and effectively pressed and limited. Furthermore, it causes the shorter cleaning objects to move abnormally such as jumping, scurrying or flipping in the high-pressure spray area and the high-speed air knife area, and even the phenomenon that the cleaning object is damaged or the components in the cleaning machine are also damaged may occur. Summary of the Utility Model

[0009] Furthermore, an elastic connecting piece is arranged between the frame and the pressing plate, and the elastic connecting piece is used to apply an elastic force to the pressing plate to form an elastic abutment limit on the cleaning object below it.
[0010] Furthermore, the pressing plate includes a connecting portion and a sliding abutting portion. The connecting portion is hinged to the frame, and the sliding abutting portion is suspended; the sliding abutting portion has at least one sliding abutting surface; when the cleaning object passes below the pressing plate, the sliding abutting surfaces respectively form a sliding abutment with the cleaning object at the corresponding height.

The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.
[0026] Now, the present utility model will be further described in conjunction with the accompanying drawings and specific implementation manners.
[0027] First embodiment
[0028] Referring to Figure 1 shown, the first embodiment provides an adaptive limit mechanism (hereinafter simply referred to as the limit mechanism) of a cleaning machine. The limit mechanism includes a cleaning machine body, and the cleaning machine body is provided with a limit pressing unit. The limit pressing unit is swingably arranged. The limit pressing unit forms a sliding contact with the cleaning object below it, and at the same time forms a corresponding swing angle, and applies pressure to the cleaning object by relying on the limit pressing unit to form an adaptive pressing and limiting setting for cleaning objects of different heights.
[0029] In this embodiment, the objects to be cleaned can be baskets, containers or other loading utensils. Since the models of the objects to be cleaned used in different cleaning workshops are different, after the objects to be cleaned with various dirt residues are uniformly recycled, they are centrally placed on the conveyor belt 7 inside the cleaning machine body and cleaned in the same cleaning machine. In this way, various actual situations where objects to be cleaned with different heights need to be cleaned simultaneously are often encountered. For example, the objects to be cleaned with different heights include the tallest object to be cleaned 2, the shortest object to be cleaned 3, and the medium-height object to be cleaned 4 located between the heights of the above two, and they move forward along the conveying direction of the conveyor belt 7 in the state shown in Figure 5 or Figure 6 . At this time, the conveying direction of the conveyor belt 7 is the conveying direction of the cleaning machine body, and generally, operations such as feeding, spraying by the spray pipe 5, drying by the air knife 6, and collecting are required in sequence to complete the cleaning of the objects to be cleaned. Among them, spraying usually uses an all-round non-dead-angle spraying direction, such as the up, down, and side directions, to clean the objects to be cleaned.
[0030] The limiting and pressing units are distributed in the spraying area and the air knife area of the cleaning machine body. In this way, only the limiting and pressing units need to be installed in the spraying area and the air knife area, and the limiting and pressing units do not need to be installed in other areas, so as to save costs and facilitate equipment maintenance and cleaning.
[0031] As Figure 1 and Figure 2 shown, the limiting and pressing unit includes a plurality of swingable pressing plates 1. Of course, the material of the pressing plate 1 can be determined according to the actual on-site situation. For example, non-metallic materials such as polyoxymethylene (i.e., POM resin), nylon (i.e., PA resin), or polypropylene (i.e., PP resin) are preferably used, or metal materials such as stainless steel can also be used. Moreover, the pressing plates 1 are arranged at intervals along the conveying direction of the conveyor belt 7. The pressing plates 1 rely at least on their own gravity to apply a downward pressure limit to the objects to be cleaned passing below them, so as to ensure that the objects to be cleaned are pressed on the conveyor belt 7 and maintain a stable conveying state, and further ensure that the objects to be cleaned will not jump, move around, or turn over due to external forces such as the spraying pressure of the spray pipe 5 or the airflow of the air knife 6 in the cleaning machine body. At the same time, by presetting the self-gravity of the pressing plate 1, the pressure of the pressing plate 1 on the surface of the objects to be cleaned can be freely adjusted to ensure that the pressure is within the production specified range, and further effectively prevent the objects to be cleaned from being scratched or damaged due to excessive pressure.
[0032] By setting the limit pressing unit to be swingable, and when the limit pressing unit forms a sliding contact with the cleaning object passing below it, the limit pressing unit can form different swing angles or swing heights to adapt to cleaning objects of different heights, and rely on the limit pressing unit to apply a downward pressure to the cleaning object, so as to realize the pressing and limiting of cleaning objects of different heights at the same time, thereby ensuring that cleaning objects of different heights will not jump, move around or flip in the cleaning machine body, nor will they be damaged by jamming.
[0033] Certainly, in other embodiments, the limit pressing unit may also include a swing rod provided with weights, so that it can also adaptively press and limit cleaning objects of different heights to prevent them from jumping, moving around or flipping.
[0034] In addition, the limit pressing unit may also be arranged in the spray area of the cleaning machine body or in the air knife area of the cleaning machine body, so that it can be applied to various types of cleaning machines with different functions.
[0035] In another preferred embodiment, the cleaning machine body has a frame 8. The upper end of the pressing plate 1 is hinged to the frame 8 of the cleaning machine body, and the other lower end is suspended above the conveyor belt 7 to form a swingable setting. And the height of the cleaning object itself is greater than the suspended height of the pressing plate 1 when it hangs naturally. At this time, the suspended height is the distance between the lower end of the pressing plate 1 when it hangs naturally and the conveyor belt 7, so as to ensure that the pressing plate 1 can abut against the surface of the cleaning object on the conveyor belt 7.
[0036] Further preferably, the frame 8 is arranged to be vertically movable up and down, and the frame 8 is also arranged to be horizontally movable, and its horizontal movement track is perpendicular to the conveying direction of the conveyor belt 7, and the direction of the horizontal movement track is the left and right direction, so as to preliminarily adjust the distance between the pressing plate 1 and the conveyor belt 7. At the same time, the frame 8 also places a certain restriction on the swing of the pressing plate 1 to avoid excessive swing amplitude.
[0037] Two pressing plates 1 with a certain distance between them are set as a pressing plate group. The pressing plates 1 of each pressing plate group are arranged in parallel, and their arrangement direction is perpendicular to the conveying direction of the conveyor belt 7.
[0038] More specifically, such as Figure 2As shown in the figure, the pressing plate 1 includes a connecting portion 11 and a sliding abutting portion 12. The frame 8 includes two fixing plates 81 for assembling the pressing plate 1. The two fixing plates 81 are spaced apart and extend along the conveying direction of the conveyor belt 7. Among them, two adjacent pressing plate groups are the first pressing plate group and the second pressing plate group. The connecting portion 11 of the pressing plate 1 on the left side in the first pressing plate group is hinged to the left end of the left fixing plate 81, and the connecting portion 11 of the pressing plate 1 on the right side in the first pressing plate group is hinged to the right end of the right fixing plate 81. The connecting portion 11 of the pressing plate 1 on the left side in the second pressing plate group is hinged to the right end of the left fixing plate 81, and the connecting portion 11 of the pressing plate 1 on the right side in the second pressing plate group is hinged to the left end of the right fixing plate 81, and swing fulcrums 111 are respectively formed. The pressing plate 1 can rotate or swing around the swing fulcrum 111 within a certain swing angle range under an external force to form different swing heights to match cleaning objects of different heights.
[0039] The sliding abutting portion 12 is arranged in a suspended manner. The sliding abutting portion 12 has a plurality of sliding abutting surfaces 121. When the cleaning object on the conveyor belt 7 passes under the pressing plate 1, the plurality of sliding abutting surfaces 121 respectively form sliding abutment with the cleaning object of the corresponding height. Of course, the number of the sliding abutting surfaces 121 can also be 1.
[0040] In this specific embodiment, each sliding abutting surface 121 is a plane or a curved surface, and a smooth surface is provided at the connection between every two adjacent sliding abutting surfaces 121 to ensure that the outer edge of the pressing plate 1 has a smooth transition surface at multiple angles, so as to ensure that the cleaning object on the conveyor belt 7 will not get stuck or flip when pushing open the pressing plate 1.
[0041] Of course, in other embodiments, the number of the pressing plates 1 in the same pressing plate group can also be 1, 3 or more than 3, which can be determined according to the actual on-site situation.
[0042] In addition, the frame 8 can also be a separately liftable or laterally movable setting, which is specifically determined according to the overall size and internal structure of the cleaning machine.
[0043] In another preferred embodiment, as Figure 3 and Figure 4 shown, the swinging trajectories of two adjacent pressing plates 1 in the conveying direction of the conveyor belt 7 are arranged in a staggered manner, that is, two adjacent pressing plates 1 in the conveying direction of the conveyor belt 7 need to be installed in a staggered manner. For example, the pressing plates 1 are respectively installed on the inner and outer sides of the fixing plate 81 perpendicular to the conveying direction of the conveyor belt 7 to ensure that they do not collide and interfere with each other when swinging.
[0044] Further preferably, an elastic connecting member is provided between the frame 8 and the pressing plate 1. The elastic connecting member is used to apply an elastic force to the pressing plate 1 to form an elastic abutment restriction on the cleaning object below it, so as to prevent the pressing plate 1 from applying an elastic force to the pressing plate 1 through the elastic connecting member when the self-gravity of the pressing plate 1 is small, and to jointly form a force restriction on the pressing plate 1 by the gravity of the pressing plate 1 and the elastic force of the elastic connecting member.
